Yeah but it's a chicken and egg thing I think. There seems to be a max price cap of about $600 for these SSD's, and so for 64gbit NAND that was ~512GB and 128Gbit NAND it is about 1TB. When they design a controller to exist during the lifetime of 256Gbit NAND there is a good chance that someone is actually going to make a 2TB drive because that much NAND would then fit inside that 'max price' so they will design the controller for that max amount. And in the same vein a contrller for the 128Gbit era would be 'OK' with a 1TB max.... if that makes sense, heh. Reply

This is explained in the article... But it is because it uses fewer large capacity NAND dies to hit the low prices. For fast writed with NAND you need lots of dies, which is why the bigger versions of this drive see better performance. Reply

Some serious question over here: is this drive a real competitor to the Sammys Evo or even Pro SSDs? I was planning on buying the 256Pro but the Crucial seems to perform better in a lot of tasks. I cannot really differentiate much but the price: 256Pro = 512MX100Reply

So far Samsung has only been sampling 3D NAND SSDs to enterprise OEMs, although they have just started providing some to the PC OEMs with the new 32-layer NAND. The XP941 is still regular MLC but Samsung it's only available for OEMs. Reply

Great bargain for the price. I heard the 256GB drive is in fact a 320 GB drive with 20% overprovisioning...that would even be more a bargain. Performance decrades less than with all other brands that only have 7%. I also like the protection and encryption on the mx 100. Still have to chose between the samsung 840 evo 250gb and the mx100. Would chose the mx100 if had better writing performance...but now i have doubts...Gonna use it for audioproduction...so lots of reads and writes that would make the samsung evo 840 a better choice right....i have a Samsung 830 128GB now and i'm satisfied with it, never failed me, but need a bigger one. Should i stick with Samsung or get the MX 100?Reply

Because Crucial is a direct seller as well as a wholesaler, they can set the MSRP much closer to wholesale/street pricing levels, so don't expect as large of a discount from MSRP to street as you would on retail brands.Reply
